Patent GB-2185631-A (GB)
Title: Spring loading device of an automatic circuit breaker by a oscillating armature electromagnet
Inventor: BOLONGEAT-MOBLEU ROBERT
IPC: H01H3/30
Filed: 1987-01-16
Abstract: An electromagnet (54) with a pivoting armature (50) is supplied by an alternating current to impose an oscillating movement to the armature. This oscillating movement is transmitted to a free wheel (34) with rollers cooperating with a shaft (30) bearing a cam (28) so that the shaft is rotated in one direction only in steps, reverse rotation being prevented by a second free wheel (36). The cam (28) engages a follower (26) to stepwise pivot a lever (20) about pivot (22) and so load a spring (24). Automatic or manual release of a latch (18) frees a toggle linkage (16) to allow contacts (10) to open. Rapid closing of the contacts is effected by the loaded spring (24) when the follower (26) is released from a cam groove (32). The armature (50) is end- or centre-pivoted, or may rotate with two arms cooperating with the ends of a U-shaped yoke. The electrical supply to the electromagnet (54) is taken from the contact line, and may be fed via diodes to produce a frequency of oscillation of the armature (50) equal to, or a multiple of, the supply frequency. When the supply is interrupted, the loading movement is interrupted immediately. <IMAGE>

Patent GB-2224557-A (GB)
Title: Flood limiting device
Inventor: GREEN JOHN BARRIE
IPC: F17D5/02
Filed: 1988-10-04
Abstract: A flow sensor S is plumbed into an inlet pipe P, and the output of the sensor is fed to an electronic timer T. Whenever water flows through the pipe P the sensor produces an electrical output signal that actuates the timer to time the flow period. Should the flow continue for a prolonged period as in the case of a burst pipe, the counter eventually reaches a predetermined time limit and sends out an actuating signal to a shut-off valve V. As shown, this valve is connected upstream of the sensor S, and shuts off the flow of water through the pipe to minimise any flood damage, until reset by a reset switch R. An override switch SW may be provided to increase the timing period following which the valve V is actuated. <IMAGE>
